PINKNEY O. VILSON, OF PATTERSON, LOUISIANA.

CONVEYER.

SPECIFICATION arming part of Letters Patent No. 481,837, dated August 30, 1892.

Application led March l2, 1892. Serial No. 424,721. (No model.)

To all whom it' may concern.-

Be it known that I, PINKNEY O. WILsoN, of Patterson, in the parish of St.. Marys and State of Louisiana, have invented a new and Improved Oonveyer, of which the following is a full, clear, and exact description.

The invention relates to conveyers such as are used in cane-mills for carrying the crushed cane from one mill to another or for conveying bagasse from the mill or for oher purposes.

The object of the invention is to provide a new and improved conveyer which is simple and durable in construction, very effective in operation, and arranged to adjust itself automatically, according to the amount of material to be conveyed.

The invention consists of a sprocket-chain carrying knives and passing over sprocketwheels, of which one is mounted in fixed journals and the other in journals carried by pivoted arms.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of the improvement, partly in section, on the line oc 0c in Fig. 2. Fig.2 is a plan view of the same, and Fig. 3 is an enlarged face view of one of the knives.

The improved carrier is provided with a suitably-constructed box A, open at the top and at its ends and placed in any desired inclined position, as is plainly shown in Fig. l. In practice the upper end of the boxAis pivotally connected with the standards O, and its lower end adjustably connected with the mill to receive the material therefrom. At the lower open end A the material or stock to be conveyed is placed and at the upper end is arranged an outlet-chute A2 for discharging the material. Above the upper end of the box A is arranged a transversely-extending shaft B, mounted to turn in suitable bearings secured to the upper ends of the standards O, erected alongside the sides of the box A.

On the outer end of the shaft B is secured a sprocket-wheel D,connected by a sprocketchain with a suitable mechanism for imparting a rotary motion to the said shaft B. On

, wheels H, mounted to turn loosely on a shaft I, extending over the lower end of the box A. The shaft I is secured in suitable bearings J, formed or secured on the free ends of arms K, pivoted at K to the standards C, previously mentioned. Each of the arms K is preferably made adjustable, as is plainly illustrated in the drawings.

In using this carrier motion is given to the chains F in the direction of the arrow a by revolving the shaft B from the drive-wheel D. The material to be conveyed is fed into the lower end A of the box, and the knives G take hold of the material, pushing the same forward in the box A to finally discharge the material over the chute A2 at the upper end of the box A.

It will be seen that the knives G engage the material and rest on the same as the shaft I is mounted in the pivoted arms K, so that the lower ends of the chains and the sprocketwheels H and shaft I have a tendency to press Vthe knives into firm contactwith the material under treatment.

It will further be seen that when the quantity to be fed forward increases the arms K swing upward, so as to admit more material under the lower parts of the chains and the knives G. As the latter are placed suitable distances apart more or less material can be carried forward in the box A between two adjacent knives, as the material is not obstructed except by those parts of the chains extending between the two knives.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A conveyer comprising a box or chute, up-

IOC)

rights adjacent to one end thereof, one e1e- Vater-shaft being journaled in bearings on said nprghts, longitudinally-adjustable arms pivoted to the said supports below. the said shaft, extending toward the opposite end of the chute, and having the other e1evator-shaft journaied in their free vertically-swinging ends, and the endless elevator mounted on the said shafts, whereby the outer end of the ele- Vator may be set at any desired distance from 1o the bottom of the chute and yet freely swixngr upward to prevent Choking, substantially as described.

PINKNEY C. VILSON.
